atonex

atonex —
Emulates a stack of filters using the atone opcode.

Description

atonex is equivalent to a filter consisting of more layers of atone with the same arguments, serially connected. Using a stack of a larger number of filters allows a sharper cutoff. They are faster than using a larger number instances in a Csound orchestra of the old opcodes, because only one initialization and k- cycle are needed at time and the audio loop falls entirely inside the cache memory of processor.

Syntax

ares atonex asig, khp [, inumlayer] [, iskip]

ares atonex asig, ahp [, inumlayer] [, iskip]

Initialization

inumlayer (optional) -- number of elements in the filter stack. Default value is 4.

iskip (optional, default=0) -- initial disposition of internal data space. Since filtering incorporates a feedback loop of previous output, the initial status of the storage space used is significant. A zero value will clear the space; a non-zero value will allow previous information to remain. The default value is 0.
